Conditions at Hondarribia in August
August: Warm Water, Small Waves
August offers the warmest water of the year at 22.6°C, but the surf still struggles to find power. Average swell height is 1.0m (3ft) and the mean period creeps up slightly to 9.2s. NW continues to dominate, with 65% of occurrences, followed by NNW at 16% and WNW at 16%. That gives plenty of waves to look at, but most are knee-to-thigh-high, with the occasional stomach-to-chest-high set when an Atlantic low pushes energy in from the northwest.
The wind regime is similar to July: NNW 19%, WNW 14%, NW 13%, and W 11%, with ideal wind at 34%. The consistent morning window is the play-southwesterly or westerly offshore breezes can groom the small NW swell into clean, weak lines. By afternoon, the north/northwest sea breeze usually takes over and turns the surface bumpy.
With air temps at 20.8°C, plenty of sunshine, and only 1.73 mm/day of rain, it is a glorious beach month. Just do not expect any kind of epic Atlantic power; August at Hondarribia is about small waves and enjoying the summer.
